    • A radiation-curable silicone rubber composition is provided which includes:(A) a specific organopolysiloxane having radiation-sensitive (meth)acryloyl groups at the both terminals of the molecular chain,(B) a photosensitizer;(C) a tetraalkoxysilane or a partial hydrolysis-condensation product thereof; and(D) optionally together with a specific organic titanium compound. This composition is curable upon irradiation by ultraviolet rays for a short time and exhibits adhesion quickly. Hence, it is useful for the bonding, coating and potting of various substrates. This composition also has a relatively weak adhesion immediately after curing, and can be peeled from the substrate with ease for a while. Hence, it is also suited for uses where repair is required. Because of a high curing rate, it can be effective for, e.g., making a process short, improving productivity and saving energy in the manufacture of electric and electronic parts.
    • 提供了一种可辐射固化的硅橡胶组合物,其包括:(A)在分子链两端具有辐射敏感性(甲基)丙烯酰基的特定有机聚硅氧烷,(B)光敏剂; (C)四烷氧基硅烷或其部分水解缩合产物; 和(D)任选地与特定的有机钛化合物一起。 该组合物在短时间内通过紫外线照射可以固化,并且快速显示粘附性。 因此,对于各种基材的粘合,涂布和封装是有用的。 该组合物在固化后立即具有相对弱的粘附性,并且可以容易地从基材上剥离一段时间。 因此,它也适用于需要修理的用途。 由于固化速度高,所以在制造电气和电子零件方面可以有效地使工艺缩短,提高生产率和节约能源。
